Visual and physical check
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Large and slow leaks will often result in air conditioning (A/C) compressor oil being drawn out with the refrigerant.
A visual inspection can localize the point where the oil gathers and identify the source of the leak.
- Check the system for corrosion which could cause refrigerant to leak
- Check that there are no loose components.
